How can I highlight "A" after "B", but do not highlight "B" itself? - gtksourceview

Suppose I want do define a special style for every character A that appears after the character B. If I do this?
<context id="AAA" style-ref="punct">
<match>[B][A]</match>
</context>
then B itself gets highlighted, which I do not want; I want to highlight only the A. How can I do this?

Use lookbehind:
<match>(?<=[B])[A]</match>
(The < of the lookbehind operator needs to be escaped in XML.)

How can I turn VSCode's sub word navigation off?

In a snake_cased language, I would want to navigate variablewise and not word_wise and also exclude sigils like #, % or / from these stops.
Example:
|$here_she_goes_again; #the pipe marks my cursor position
With one Ctrl+Right, I want to land on the space before the semicolon,
$here_she_goes_again|; #the pipe marks my cursor position
then, with a Ctrl+Left, I want to return to the beginning of the line.
|$here_she_goes_again; #the pipe marks my cursor position
Somebody got this to work?
Put this into your settings.json:
"[javascript]": {
"editor.wordSeparators": "`~!##%^&*()-=+[{]}\|;:'",.<>/?"
}
Use whatever your language identifier is. I deleted the $ from the default separators to get your example to work for javascript. You can remove the other characters you indicated. The underscore was already not in the default for me. Just make sure those characters are not in the language-specific setting shown above.
You can use the extension Select By and the command moveby.regex
You are able to define a regex to search and bind this to Ctrl+Left and another to Ctrl+Right
In the key binding you can limit this to a particular languageID.

How to add a small straight line (I mean like this: a̅ b̅ X̅) onto a character inside a string?

I want to add small straight line onto some desired characters/numbers inside a string inside textview. I couldn't find a solution. Maybe using NSMutableAttributedString. Meanwhile, I mean doing this programmatically. There is strikethrough style, but not overstrike style. Or maybe adding the letters "a" and "_" with different .baseline values. But how to add both characters onto each other then?
Is it possible?
EDIT: Due to make a try for the helpful answers below, I think to make the line at a spesific height is needed. "A\u{0305}" makes the up line very close to the character, as if it sticks. Is there a way to make it at specific height? For example, if we assume that all the keyboard-inputted characters are written inside every single boxes, the ceiling side of these boxes could be lined?
So this (note: see edit below) appears to be an "a tilde ogonek" (it's Lithuanian).
You can write it for instance as follows using these two Unicode characters:
let atildeogonek = "\u{0105}\u{0303}"
let title = "How to add a small straight line (I mean like this: \(atildeogonek)) onto a character inside a string?"
The first character is the a with an ogonek, the second one is the tilde.
EDIT: The initial question specifically asked about the character ą̃ ("a tilde ogonek") in the title, and I used this code to demonstrate how to use Unicode characters in a Swift string. After posting this answer, the question was edited to be more general about "a line above a character".
Programmatically, you could use a function like this:
func overline(character: Character) -> Character? {
return "\(character)\u{0305}".first
}
That will take a character as input and return a new character (glyph) that has had the Unicode combining overline character added to it. It will return nil if adding the combining overline character fails.
The code print(overline(character:"A")!), for example, returns "A̅"
Or, if you want to add an overline to every character in a string, you could use a function like this:
func overline(characters: String) -> [Character?] {
return Array(characters).map { return "\($0)\u{0305}".first
}
}
(I'm not sure if there are any characters for which the above will fail, so I'm not sure if force-unwrapping the result is safe. Thus I left the result of both functions to be optional Character/Array of Character.)
You can easily find the unicodes of ā or ą̃ by using the xcode's own Character Viewer. Just follow the following steps :
hit : Control + Command + SpaceBar
If you get a compact one like this, click the upper right corner icon to expand it.
When expanded, Click the settings gear in the corner . Select customize list.
select Enclosed Characters
Go down to the bottom and open Code tables then add Unicode.
Now, just search for your required Character and you can check its unicode value. here i am searching ā
to print unicode's value :
print("\u{0101}")

In VSCode, how do I multi-cursor the ending of all symbols?

I'd like to add a suffix to all occurrences of a variable in a file (eg. pluralizing a variable number --> numbers).
VSCode offers a multiselect option thru the default "cmd+d", or editor.action.addSelectionToNextFindMatch. However, after I do this over all occurrences of number, the entire variable is selected. I really just need the cursor to be at the very end, so I can add an s. I would like not have to retype numbers.
How can I achieve this?
As an alternative, I use a regex:
\b(var1|var2|var3)\b
And I replace it with the same content $1 (since I capture the variable name in a group with ()) followed by 's': $1s
I would just copy the variable first. So:
Double-click your variable and Ctrl-C
Ctrl-F2 selects all occurences
Ctrl-V and add your 's'
The regex method is better if you have a few variables to change, but not if you have only one or two to change. Really simple to create a macro if you would be doing this a lot - you could get it down to a single keychord.
[This unfortunately selects occurrences of var1 and someOtherVar1 (the Var1 part) - so if this is a problem better to use a regex as it is easier to exclude instances of the var1 term appearing within another word, like someVar1 that you do not intend to change.]

vim: how to select and replace one word for all its appearance?

In a file, I wish to replace all "middle" with "medium", I dont' wish to use
:%s:middle:medium:g
I wish to
1. put the focus on the word of "middle"
2. press 'gd' to high light it,
3. and then do something to replace all its appearance(multiple places) into "medium".
What's more, does vim provide that when I replace a word, while typing, all its locations will display the same change?
How to do this, should I use normal mode or visual mode?
First question
You can use :help gn:
* jump to the next occurence of the word under the cursor
`` jump back
cgnmedium<Esc> change it to whatever you want
. repeat change on next occurrence
. repeat change on next occurrence
. repeat change on next occurrence
You can map it if you want:
nnoremap <key> *``cgn
Second question
No but you can google for "multiple cursor vim" if you really want such a feature.

How to do search and replace involving fields in Microsoft Word?

I have a Word document with fields of the reference variety, which occur in the form "[field].[field]"--in other words, there's a period between the two fields. I want to globally replace this with a space.
Word offers the ^d special character to search for fields, but for some reason the query "^d.^d" does not find anything. However, ".^d" does. Now comes the problem, however--what do I specify as the replacement text in order to retain the field code? If using regular expressions, I could use a "Find What Expression" such as \1, but with regexp ("wild card") mode the ^d is not permitted.
I guess I could write a macro...
I would like to add to Bibadia's solution.
An example of an index entry field; we want to change a name we misspelled.
Make sure hidden formatting is displayed (toggle with SHIFT+CTRL+F8).
Make sure wildcards option is not selected. To search for fields, use the opening and closing field braces code (optionally use ^w for spaces, as Bibadia suggested):^19 XE "Deo, John" ^21
Replace won't recognize field braces character, but will allow to insert the clipboard's content. ;). To do that, insert in text the correct entry. CTRL+F9 to insert field and type:XE "Doe, John"
Select the field above and copy
Use ^c in the replace box
Hit Replace All
Ta-da!
It's usually better to go the macro route when finding fields because, as you say, the find algorithm that Word uses doesn't work the way you might hope with fields.
But if you know exactly what the fields contain, you can specify a search pattern that will probably work (however not in wildcard mode).
For example, if you want to look for figure number field pairs such as
{ STYLEREF 1 \s }.{ SEQ Figure \* ARABIC \s 1 }
(which would typically be the same set of fields everywhere in the document)
If you only really need to look for the following:
{ STYLEREF 1 \s }.<any field>
you could ensure that field codes are displayed and search for
^d STYLEREF 1 \s ^21.^d
or
^19 STYLEREF 1 \s ^21.^19
If you need to be more precise, you can spell out the second field as well.
"^d" only works for finding the field beginning, not the field end.
It's a shame that ^w wants to find at least 1 whitespace character because otherwise it would be more robust to look for
^19^wSTYLEREF^w1^w\s^w^21.^19
Perhaps someone else knows how to work around that without using wildcards?
Torzaburo,
I suggest that you do this using a macro. You can start by recording the macro, and later refining your processing steps within the macro.
First turn on the hidden characters by navigating to Home > Paragraph > toggle the show/hide Paragraph symbol. Also, select all and toggle the field codes on (right-click and select "Toggle Field Codes".
Open a new blank Word doc in addition to the one you have open. You will use this later. Start the macro recording and find the field using the "^d" (field code) as you said.
When the field is found, copy only the field text within the brackets, and not the full field reference. While the macro is still recording, ALT + TAB to the new blank document and paste the field code in as plain text.
At this point, do the necessary find & replace processing to the field codes. Highlight the processed field codes, copy, ALT + TAB back to the original document, and paste back between the { } brackets.
Stop the macro recording. Add any further custom processing to the macro VBA.
Select-All and re-toggle the field codes. Update the field codes.
You don't need a macro. Just toggle all field codes on by using Alt+F9. Then do a find and replace for what you want to change. Once the replacement is complete, use Alt+F9 again to toggle the field codes back off.
Disclaimer: I didn't originate this solution, but it's clean and elegant and I thought it should be included here:
(Adapted from Search & Replace Field Codes in Word):
Create or find a single instance of the field you want to convert text to
Toggle Field Codes visible (AltF9)
Copy the code for the field you want to use to the Clipboard (highlight and CtrlC)
Open the Replace dialog box (CtrlH), insert the text you want to replace in the Find What box and then enter ^c in the Replace With box.
This will replace your text with the contents of the Clipboard, turning it into the field code you copied in step 3. It also copies formatting information (font, color, etc.), to control how the field will appear when hidden. (Caveat: I've tested this with Word 2003 under Windows 7 only.)
Coming in late on this, probably way too late for Beth (sorry Beth). And this may not be quite what Beth was looking for. But for anyone interested ...
It sounds like Beth may have created captions throughout the document using INSERT CAPTION (hence the presence of field codes). This means these captions will have been (automatically) created in CAPTION style.
To globally replace the separator "." with " " (space) in such captions, take two steps:
[1] Go to REFERENCES | INSERT CAPTION, then click on NUMBERING and replace the SEPARATOR "." with "EM-DASH". This will replace all separators in captions for the selected label in the CAPTION Window. If you have other labels in use in the document (e.g. FIGURE), select the other labels one by one and repeat this process.
[2] Do a find/replace searching for special character "em-dash" (^+) in style CAPTION, replacing with " ". Click REPLACE ALL.
Voila!
NOTE: This presumes that em-dash does not appear in the caption text anywhere. If it does, then you'll need to do a pre- and post- "fiddle" to ensure these em-dashes are not touched by the global replace above.
The "pre-fiddle" is to do a global find/replace across captions, replacing the em-dash ("^+") with some other string (e.g. "EM-DASH") that doesn't ever occur in any caption's text. Then you do the separator change as described above. Finally, the "post-fiddle" is to restore the em-dashes that were in the captions, by doing a global replace of the string "EM-DASH" with the actual em-dash character "^+".
